A pentagon has no parallel lines.
Here are three shapes that have two pairs of parallel lines: square parallelogram rectangle There are many polygons with at least two pairs of parallel lines. hexagon (has 3 pairs of parallel lines) octagon (has 4 pairs) decagon (has 5 pairs)
up to four pairs is the answer
A regular pentagon has no parallel lines.
A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
A diamond has two pairs of parallel lines.
A rhombus has 2 pairs of parallel lines.
A regular dodecagon has six pairs of parallel lines.
it has 2 pairs of parallel lines
it has too parallel lines!
